LYSOSOMES - Surrounded by a single membrane.- Derived (buds of) from Golgi apparatus.- Contains degradative enzymes for digesting foreign bodies,
cellular wastes and other toxins.
PRIMARY LYSOSOME - is a membrane bounded sac that buds off from the GA apparatus
SECONDARY LYSOSOME - is a primary lysosome that fuses/ phagocytosis with any solid material in the cell (e.g. organelle or
bacteria)
Cytoskeleton Functions• Support and shape
cell• Anchor many
organelles• Move substances from
one part of the cell to another
• Enable cell division• Enable cell movement
CYTOSKELETON -A dynamic internal framework/ scaffolding
FUNCTION;1 .Contributes to cell shape
2 .Coordinates cytoplasm and its components )e.g. act in cell division, muscle movement(
